A simple and easy-to-use music engine support playing-while-downloading feature.

• Playing music while downloading.
• Cache downloaded music to disk. You can specify the cache key.
• Tracking downloading and playing progress.
• Background playing.

All dependences are setted as sub module.

• AFDownloadRequestOperation:
• AFNetworking
• ARC only

Just playing:

NCMusicEngine *player = [[NCMusicEngine alloc] init];
player.delegate = self; // If you need...
[player playUrl:url];

NCMusicEngine generates cache key from your music url by default. If you need to manage it yourself, you could use the following method:

[player playUrl:url withCacheKey:@"cachekey"];

Tracking progress please use the following delegates:

- (void)engine:(NCMusicEngine *)engine didChangePlayState:(NCMusicEnginePlayState)playState;
- (void)engine:(NCMusicEngine *)engine didChangeDownloadState:(NCMusicEngineDownloadState)downloadState;
- (void)engine:(NCMusicEngine *)engine downloadProgress:(CGFloat)progress;
- (void)engine:(NCMusicEngine *)engine playProgress:(CGFloat)progress;

I'll keep polishing this engine and keep adding new features. If you have any problems when using this engine, please feel free to drop me an issue or contact me:
